Scientifically accurate paleoart of Styracosaurus, a herbivore Ceratopsidae dinosaur from the Campanian age of the Late Cretaceous (about 75.5–75 million years ago). One long, straight horn on the nose and only small horns or knobs above the eyes. A short frill with four to six long spikes radiating backward from its top edge. Reference: Styracosaurus is an extinct genus of herbivorous dinosaur from the Late Cretaceous of North America. It had four to six long parietal spikes extending from its neck frill, a smaller jugal horn on each of its cheeks, and a single horn protruding from its nose, which may have been up to 60 centimeters long and 15 centimeters wide. The function or functions of the horns and frills have been debated for many years. Anatomy: a large, hooked, parrot-like beak; quadrupedal with pillar-like hind legs; front legs semi-erect with the elbows slightly out and the fingers pointing forward and outward, NOT palms-down; skin of large rounded scales, some with small conical bumps. Full body in side view, whole animal visible, standing in a Late Cretaceous coastal floodplain like the Dinosaur Park Formation of Alberta, with conifers, ferns and early flowering plants by a river, no grass. Natural history museum illustration style, realistic textures and natural daylight, muted natural colors. No text, no labels, no humans, no modern objects.
